CABLE OR. BELT TIGHTENER.

srncrrrcarron forming part of Letters Patent No, 317,692, dated May 12, 1885.

Application filed March 25, 1885. (No model.)

To all whom it may concern.-

Be it known that I, J. HILL WRITING, of Detroit, in the county of YVayne and State of Michigan, have invented new and useful Improvements in Cable or Belt Fasteners; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to a new and useful improvement in tighteners for ropes and belts; and the invention consists in the peculiar construction and arrangement of the parts, all as hereinafter described.

In the drawings which accompany this specification, Figure l is a diagram view of an endless traction c'able provided with my improved tightener, as arranged in different positions. Fig. 2 is a detached perspective view of my tightener, showing details of construction.

In the drawings, A is an endless traction cable, to which my tightener is shown applied in two different positionsin one position in connection with the horizontal run of the cable, and in the other position with a vertical run of the cable.

B is a block, which may be of almost any of the various shapes and forms now manufactured in large numbers for all kinds of hoistingtackle. For the purpose of a tightener I pro vide such a block at two opposite ends of its frame or shell with laterally-projecting ears, hooks, or guides, a, for which such points of attachment, as provided for the ordinary use of the blocks, may be utilized. These ears, hooks, or guides are intended to hold the block in position by their engagement upon two fixed parallel bars, 0. These bars are secured at right angles to the rope, and are of suitable length to admit the free rise and fall of the block under the varying tension of the rope they are provided with suitable fastening devices upon their ends, by means of which they can be secured readily to any fixed support, or hanged gallows-fashion from a ceiling or rafters overhead.

Ordinary gas-pipe, with proper couplings, will be found very serviceable to construct the whole rig.

To get the desired tension of the cable, it will be generally found necessary to use weights, which may be attached in any convenient manner to the hook of the block.

If this tightener has to be applied to a vertical run of cable, the weight has to be led around a pulley, as shown in Fig. 1.

It will be seen that such a tightener is inexpensive and quickly constructed, and consists of such parts as are always at hand or readily procured.

It is clear that a belt-tightener may be constructed in the same manner as the cabletightener above described, by substitntinga pulley for the sheave of the block; but as there is difficulty of finding suitable blocks which will admit a pulley of suitable width for a belt-tightener, my invention is of less use for this purpose.

What I claim as my invention is- In a tightener for cables and belts, a block having laterally-projecting hooks, eyes, or guides secured to its frame, in combination with two parallel bars secured to a fixed support at right angles to the cable, all arranged and operating substantially as described.
